Weird Client Access problem

Our setup:  V4R4, Client Access V3R2M0 (latest SP installed), Win 98SE.

I've installed CA, connected to the 400 thru TCP/IP, gotten a signon 
session, and logged in.  I'm trying to map \\AS400\QDLS to drive J:, with 
no success.  Whenever I try, I can hear the 400 banging away like it's 
trying to do something, then I get a Windows dialog: \\AS400\QDLS is not 
accessible. I can map other \\AS400\ folders, just not QDLS.  The strange 
thing is I CAN map QDLS on other PCs with no problem.  I've verified the IP 
address and the subnet mask, everything's cool in that respect.  During 
install, I did nothing different than I did on any of the other PCs (other 
than the static PC address, naturally).

I see no messages in DSPLOG, QSECOFR or QSYSOPR job logs.

Any ideas?
